The formula to calculate Perimeter of Semicircle (P) is:
\[ P = \left(\frac{\pi}{2} + 1\right) D \]
Where:
The Perimeter of Semicircle is the total distance around the edge of the Semicircle.
The Diameter of Semicircle is defined as the length of the longest chord of the semicircle.
Let's assume the following values:
Using the formula:
\[ P = \left(\frac{\pi}{2} + 1\right) D \]
Evaluating:
\[ P = \left(\frac{\pi}{2} + 1\right) \times 20 \]
The Perimeter of Semicircle is 51.4159265358979.
